Process for preparing novel dihydropyridine deriva-- tives and salts thereof represented by the general formula (1).
[wherein R', R2 and R4 are each a lower alkyl group; R3 is a nitro group or a lower alkyl group which may have 1 to 3 halogen atoms as the substituents; R5 is a phenyl group which may have 1 to 3 substituents selected from the group consisting of a lower alkoxy group, a halogen atom, a lower alkylthio group, a hydroxyl group, a lower alkonyloxy group, a tetrahydropyranyloxy group, a lower alkoxy-lower alkoxy group; and A is an unsaturated straight- or branched-chain hydrocarbon residue]. The novel dihydropyridine derivatives and salts thereof are useful as coronary blood flow improving agents such as coronary vasodilator, hypotensive agent, prophylaxis and treating agents for thrombosis, phosphodiesterase inhibitory agents, peroxidized lipid metabolism lowering agents, antiinflammatory agents as well as anti-tumorigenic agents.
由通式(1)表示的新型二氢吡啶衍生物及其盐的制备方法。
[其中 R'、R2 和 R4 各为低级烷基;R3 为硝基或低级烷基,其取代基可为 1 至 3 个卤素原子;R5 是苯基,可具有 1 至 3 个取代基,这些取代基选自低级烷氧基、卤素原子、低级烷硫基、羟基、低级烷酰氧基、四氢吡喃氧基、低级烷氧基-低级烷氧基组成的组;以及 A 是不饱和直链或支链烃残基]。新型二氢吡啶衍生物及其盐类可用作冠状动脉血流改善剂,如冠状动脉血管扩张剂、降血压剂、血栓预防和治疗剂、磷酸二酯酶抑制剂、过氧化脂质代谢降低剂、抗炎剂以及抗肿瘤剂。
